Bosch Power Tools



Always use undamaged wheel flanges that are of cor-
rect diameter for your selected wheel. 

Proper wheel 

flanges support the wheel thus reducing the possibility of 
wheel breakage.



Do not use worn down reinforced wheels from larger 
power tools. 

Wheels intended for larger power tools are 

not suitable for the higher speed of a smaller tool and may 
burst.



The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power 
tool. 

Incorrectly sized accessories cannot be adequately 

guarded or controlled.



The arbour size of wheels and flanges must properly fit 
the spindle of the power tool. 

Wheels and flanges with ar-

bour holes that do not match the mounting hardware of the 
power tool will run out of balance, vibrate excessively and 
may cause loss of control.



Do not use damaged wheels. Before each use, inspect 
the wheels for chips and cracks. If power tool or wheel 
is dropped, inspect for damage or install an undam-
aged wheel. After inspecting and installing the wheel, 
position yourself and bystanders away from the plane 
of the rotating wheel and run the power tool at maxi-
mum no load speed for one minute. 

Damaged wheels will 

normally break apart during this test time.



Wear personal protective equipment. Depending on 
application, use face shield, safety goggles or safety 
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and shop apron capable of stopping 
small abrasive or workpiece fragments. 

The eye protec-

tion must be capable of stopping flying debris generated 
by various operations. The dust mask or respirator must be 
capable of filtrating particles generated by your operation. 
Prolonged exposure to high intensity noise may cause 
hearing loss.



Keep bystanders a safe distance away from work area. 
Anyone entering the work area must wear personal 
protective equipment. 

Fragments of workpiece or of a 

broken accessory may fly away and cause injury beyond 
immediate area of operation.



Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting ac-
cessory may contact hidden wiring or its own cord. 

Cut-

ting accessory contacting a “live” wire may make exposed 
metal parts of the power tool “live” and could give the op-
erator an electric shock.



Position the cord clear of the spinning accessory.  

If you 

lose control, the cord may be cut or snagged and your hand 
or arm may be pulled into the spinning wheel.



Never lay the power tool down until the accessory has 
come to a complete stop. 

The spinning wheel may grab 

the surface and pull the power tool out of your control.



Do not run the power tool while carrying it at your side. 

Accidental contact with the spinning accessory could snag 
your clothing, pulling the accessory into your body.



Regularly clean the power tool’s air vents. 

The motor’s 

fan will draw the dust inside the housing and excessive ac-
cumulation of powdered metal may cause electrical haz-
ards.



Do not operate the power tool near flammable materi-
als. 

Sparks could ignite these materials.



Do not use accessories that require liquid coolants. 

Us-

ing water or other liquid coolants may result in electrocu-
tion or shock.

Kickback and related warnings



Kickback is a sudden reaction to a pinched or snagged ro-
tating wheel. Pinching or snagging causes rapid stalling of 
the rotating wheel which in turn causes the uncontrolled 
power tool to be forced in the direction opposite of the 
wheel’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by 
the workpiece, the edge of the wheel that is entering into 
the pinch point can dig into the surface of the material 
causing the wheel to climb out or kick out. The wheel may 
either jump toward or away from the operator, depending 
on direction of the wheel’s movement at the point of pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.



Maintain a firm grip on the power tool and position your 
body and arm to allow you to resist kickback forces. Al-
ways use auxiliary handle, if provided, for maximum 
control over kickback or torque reaction during 
start-up. 

The operator can control torque reactions or 

kickback forces, if proper precautions are taken.



Never place your hand near the rotating accessory. 

Ac-

cessory may kickback over your hand.



Do not position your body in line with the rotating 
wheel. 

Kickback will propel the tool in direction opposite 

to the wheel’s movement at the point of snagging.



Use special care when working corners, sharp edges, 
etc. Avoid bouncing and snagging the accessory. 

Cor-

ners, sharp edges or bouncing have a tendency to snag the 
rotating accessory and cause loss of control or kickback.



Do not attach a saw chain, woodcarving blade, seg-
mented diamond wheel with a peripheral gap greater 
than 10 mm or toothed saw blade. 

Such blades create 

frequent kickback and loss of control.



Do not “jam” the cut-off wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth of cut. 

Overstressing the wheel increases the loading and suscep-
tibility to twisting or binding of the wheel in the cut and the 
possibility of kickback or wheel breakage.



When wheel is binding or when interrupting a cut for 
any reason, switch off the power tool and hold the pow-
er tool motionless until the wheel comes to a complete 
stop. Never attempt to remove the cut-off wheel from 
the cut while the wheel is in motion otherwise kickback 
may occur. 

Investigate and take corrective action to elimi-

nate the cause of wheel binding.
